sample: a portion, piece, or segment regarded as representative of a whole.

sand: suspended sediment or bed material with a particle-size of 0.062-2.0 mm in diameter.

scrubland: a growth or tract of stunted vegetation.

scud: an aquatic macroinvertebrate; an amphipod of the phylum Arthropoda, class Crustacea; have many appendages and two pairs of antennae; are very fast swimmers; look like shrimp; somewhat sensitive to pollution.

secondary consumer: an organism that feeds on primary consumers; a carnivore.

second of latitude (or longitude): a unit of measure equal to 1/60 of a minute latitude or longitude.

sediment: loose materials such as rock fragments and mineral grains that have been transported by wind, water, or glaciers.

sediment load: total sediment in a sample of water. There are three categories of sediment: suspended load, dissolved load, and bed load.

species: a group of organisms that share similar characteristics and can interbreed with one another to produce fertile offspring.

stream: a body of water flowing in a natural channel and containing water at least part of the year.

striped bass: Roccus saxatilis. A food and game fish of North American coastal waters, having dark longitudinal stripes along the sides.

suspended sediment: very fine soil particles that remain in suspension in water for a considerable period of time without contact with the bottom, due to the upward components of turbulence and currents.
